Can't find default 'Compliments' module

The default compliments are running fine when I startup MM, but I want to edit them and cannot find them in the code. The compliments module in config.js only lists the following:

{
module: "compliments",
position: "lower_third"
},

I can’t seem to figure out where they would be as every forum response to this is to look in config.js, and the README file in the modules directory wasn’t helpful for me. I’m an absolute beginner so if someone could explain this to me simply I would be very appreciative
